354efaec38 bpf: Fixes a snprintf truncation warning
gcc v9.3.1 reports:

bpf.c: In function ‘bpf_get_work_dir’:
bpf.c:784:49: warning: ‘snprintf’ output may be truncated before the last format character [-Wformat-truncation=]
  784 |  snprintf(bpf_wrk_dir, sizeof(bpf_wrk_dir), "%s/", mnt);
      |                                                 ^

  784 |  snprintf(bpf_wrk_dir, sizeof(bpf_wrk_dir), "%s/", mnt);
      |  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix this simply checking snprintf return code and properly handling the error.

358abfe004 Revert "bpf: replace snprintf with asprintf when dealing with long buffers"
This reverts commit c0325b0638.
It introduces a segfault in bpf_make_custom_path() when custom pinning is used.

This happens because asprintf allocates exactly the space needed to hold a
string in the buffer passed as its first argument, but if this buffer is later
used in strcat() or similar we have a buffer overrun.

As the aim of commit c0325b0638 is simply to fix a compiler warning, it
seems safe and reasonable to revert it.

b262a9becb bridge: Fix output with empty vlan lists
Consider this configuration:

ip link add br0 type bridge
ip link add vx0 type vxlan dstport 4789 external
ip link set dev vx0 master br0
bridge vlan del vid 1 dev vx0
ip link add vx1 type vxlan dstport 4790 external
ip link set dev vx1 master br0

	root@vsid:/src/iproute2# ./bridge/bridge vlan
	port    vlan-id
	br0      1 PVID Egress Untagged

	vx0     None
	vx1      1 PVID Egress Untagged

	root@vsid:/src/iproute2#

Note the useless and inconsistent empty lines.

	root@vsid:/src/iproute2# ./bridge/bridge vlan tunnelshow
	port    vlan-id tunnel-id
	br0
	vx0     None
	vx1

What's the difference between "None" and ""?

	root@vsid:/src/iproute2# ./bridge/bridge -j -p vlan tunnelshow
	[ {
		"ifname": "br0",
		"tunnels": [ ]
	    },{
		"ifname": "vx1",
		"tunnels": [ ]
	    } ]

Why does vx0 appear in normal output and not json output?
Why output an empty list for br0 and vx1?

Fix these inconsistencies and avoid outputting entries with no values. This
makes the behavior consistent with other iproute2 commands, for example
`ip -6 addr`: if an interface doesn't have any ipv6 addresses, it is not
part of the listing.
